LTC3859AMPFE#TRPBF Overview
In the 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package, the switching controller meets most application requirements. dc motor controller is suitable for 3 output generation. Tape & Reel (TR) solid enclosure protects the pmic. A total of Transistor Driver dc switching's outputs can be handled by it. Voltages 4.5V~38V are the dc control's supply voltage and operating voltage, respectively. Qualified to work in a -55°C~150°C TJ dc switcher. Using this switching controller, it is possible to switch at 115kHz~835kHz 350kHz~535kHz. dc dc regulators can be carried out with Surface Mount. In order to control switching efficiently, the dcdc regulator features Enable, Frequency Control, Power Good, Soft Start, Tracking. Connected to a DUAL SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. switching converters terminal (s) are designed to be at DUAL. The 38 terminations can be used for a wide range of dc switching. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's voltage input is 12V. LTC3859 can be searched for other relevant dc to dc converter ics. The type is a particular Switching Regulator or Controllers of switching converter. dc dc voltage regulators should have a minimum input voltage of 4.5V. DC regulator outputs 5.4V voltage based on test statistics.
